Species List: 22-12-2017, Bornella Reef, Old Woman Island, off Mudjimba, Sunshine Coast, Qld.

33 species sighted at Bornella Reef, Old Woman Island, off Mudjimba, Sunshine Coast, Qld. 22-12-2017.

Julie, Terry, Gary and David on this excursion consisting of 1 x 90 minute and 1 x 83 minute dives in water depths from 11 m to 15 m. 8 m viz, 24 C water temp and slight surge.

Our original intention was to head up to the Arkwright Shoals for our diving but mechanical issues saw us taking a much shorter trip to Old Woman Island. The shallower depth gave us longer bottom times. Finds worth mentioning include Ardeadoris egretta, Chromodoris magnifica and an undescribed species, Bornella sp. 1 that is new to our list.
